🔴 Gossamer Bio is trading 5.29% down today amid a 4.24% biotech sector ETF decline

Gossamer Bio is trading 5.29% down now at $0.16 after broader biotech weakness.

• The biotech sector ETF is down 4.24%, making sector pressure the clearest explanation for the decline.
• No new company-specific announcement dated September 1, 2026, was identified in available coverage.
• The latest major update remains Gossamer Bio’s August 21 structured financing, potentially providing up to $250 million, though much depends on regulatory milestones; broader risk-off sentiment and weaker equities may also be adding pressure.
